The Flish.

Flish are a group of air-breathing ray-finned fish in 200 million AD. With their pectoral fins adapted as wings, they are capable of true, powered flight, and occupy many aerial niches of Pangaea II, being particularly diverse along the coastlines of the Global Ocean, as well as well-watered terrestrial habitats such as the Northern Forest. One of the Flishes then squawked at you.
